EMANUEL FOLGMAN, OF BROOKLYN, NEW YORK.

TORCH.

Application filed October 22, 1921.

To all w 710m it may concern Be it known that I, EMANUEL FoLcMAN, acitizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Torch, of which the following is a full,clear, and exact description.

The present invention relates to new and useful improvements inself-blowing torches, and it pertains more particularly to animprovement on the torch shown and described in United States LettersPatent No. 1,330,696 and No. 1,379,544, granted to me February 10, 1920,and May 24:, 1921, respectively. In the torch shown and described inthese patents, it has been found in actual practice that duringoperation, a pressure is generated within the main fuel chamber, andthat when the flame is extinguished this pressure being relieved throughthe wick tube, forces fuel ahead of it owing to the wick being saturatedwith said fuel, and causes a discharge of the fuel through the burneropen %t is the primary object of the present invention to provide meansfor relieving the pressure in the main fuel reservoir without causing adischarge of fuel from the wick in the wick tube.

It is a further object of the invention to so construct this dischargeelement that it is bodily removable from the wick tube for the purposeof cleaning and the like.

lVith the above and other objects in view, reference is had to theaccompanying drawings, in which Fig. 1 is a view in side elevation of aportion of a torch constructed in accordance with the present invention;

Fig. 2 is a detail View partly in section of the wick tubes of the torchdescribed in the aforementioned. patents, said view showing theimprovement in place therein.

Referring more particularly to the drawings, the reference character 5designates the body of the torch, and the upper portion thereof asshown, forms the main fuel reservoir of the torch. Leading from the topwall 6 of the main fuel reservoir is a wick tube 7, and said wick tubeforms an overlying retort for a burner 8. The reference character 9designates the burner pipe, and said burner pipe 9 is provided with adischarge opening 10.

Mounted in the wick tube 7, is a wick 12,

Serial No. 509/1663.

and in practice the wick is saturated with the fuel in the body 5 of thetorch, it being understood that said wicks extend downwardly thereino.In the present instance, a small vent tube 15 is mounted in the wicktube 7, and occupies a position preferably between the wick 12 and theouter wall of the wick tube in which it is placed. This vent tube hasits upper end extended to a point adjacent the burner cap 16, and isprovided with a loop or the like 17 with which a suitable tool may beengaged in placing or removing said vent tube 15. The lower end of thevent tube 15 terminates at a point substantially flush with the upperwall of the main. reservoir 5, and this tube serves to establishcommunication between the main reservoir 5 and the passage 30 of theburner cap 16.

The device operates in the following manner:

During the operation of the torch as heretofore stated, a pressure isgenerated within the main fuel reservoir 5 and when the torch isextinguished said pressure in passing through the wick tube 7 forces theliquid fuel with which the wick is saturated, through the burner opening10. When, however, the vent tube 15 is positioned in the wick tube 5,immediately upon extinguishing the torch, the pressure in the main fuelreservoir is relieved by the vent tube 15, said pressure passing throughthe vent tube to the passage 30 of the burner cap, and from thence tothe burner tube 9 and out through the burner opening 10 thereof.

By this construction it is apparent that the pressure in the mainreservoir is relieved without passing through the entire length of thewick in the wick tube. and, therefore, the pressure is relieved withouta discharge of fuel through the burner opening, as is the practice whenthe vent tube is not employed.

lVhile in the present embodiment of the invention, the by-pass tube hasbeen shown as positioned within the wick tube, it is obvious that thesame be exterior thereof without departing from the scope of the presentinvention, since a tube of this character could be employed to dischargedirectly into the atmosphere on the exterior of the wick tube, ifdesired.

I claim:

1. In a torch of the class described, a main reservoir, a wick tube,said wick tube having one of itsends formed, with a discharge opening, avent tube carried by said Wick tube and conforming to the shape thereof,said vent tube extending throughout the wick tube from the mainreservoir to the discharge opening thereof and means having one of itsends formed With discharge opening, means for by-passlng pressure in themain reservoir, said means comprising a by-pass tube adapted toestablish communication between said reservoir and the atmosphere and aloop associated with said by-passing tube, said loop forming means forengagement With a tool to remove the by-pass tube from the wick 20 tube.

EMANUEL FOLGMAN.
